Buy more and keep it safe yourself and give it to them later instead of asking them to keep track of $20 of Bitcoin

I know what you mean. I wouldn’t ask them to hold onto the Satscard though - I’d safeguard it myself until they’re ready.
I kind of like the idea of someday being able to say “I traded $20 for this” and be able to give them something of significantly larger “value” to make the point
